2. A roadway having a traflic marking line in its upper surface consisting of material dis tinguishably colored from the road surface material and set in the road surface, and a trough receiving said material and set in the road surface, said trough comprising complemental flanged elements of which certain flanges are corrugated and nest one within the other, fasteners passing through the flanges to assemble the trough sections, and an anchor strip interposed between the connected flanges, and itself corrugated to correspond with the corrugations in the flanges, and spacers interposed between the flanges and the anchor strip and dished and bulged respectively on opposite faces to respectively receive and enter the peaks and hollows of the corrugations.

3. A roadway having a traflic marking line in its upper surface consisting of material distinguishably colored from the road surface material and set in the road surface, and a trough receiving said material and set in the road surface and comprising a duality of. complemental flanged elements of which corresponding flanges are corrugated with that of one element nesting in that of the other element, and fasteners engaged with the nested flanges and securing the elements together.

4. A roadway having a traffic marking line in its upper surface consisting of material distinguishably colored from the road surface material and set in the road surface,and a trough receiving said material and set in the road surface, the trough comprising a duality of complemental flanged elements and an anchor strip, corresponding flanges of said elements being corrugated and the anchor strip being corrugated and interposed between the corrugated flanges, and fasteners engaging the corrugated flanges to secure them and the intervening anchor strip in nested relation.

5. A roadway having a traflic marking line in its upper surface consisting of material distinguishably colored from the road surface material and set in the road surface, and a trough receiv ing said material and set inthe road surface, the trough comprising a duality of complemental flanged elements and an anchor strip, corresponding flanges of said elements being corrugated and the anchor strip being corrugated and interposed between the corrugated flanges, and fasteners engaging the corrugated flanges to secure them and the intervening anchor strip in nested relation, the anchor strip being materially wider than the corrugated flanges and so disposed between them that its upper edge projects into the trough and its lower edge extends materially below the lower edges of said flanges.
